HoIs'rrNe AND ruL'LING TOOL.

Application filed January 7, 1924, Serial No. 684,756.

To all whom it may concern.

Be it known that I, MARTIN GR 'U, citizen of the United States, residing at Lovelady, in the county of Houston and State of Texas, have invented certain new and useful Improvements in Hoisting and Pulling Tools, of which the followingis a specification.

This invention relates toa hoisting and pulling tool and particularly to an improvement upon my prior Patent No. 1,432,998 dated Oct. 24, 1922 by which the character of tool therein shown is adapted for/universal farm uses.

In common practice separate tools have been required for farm hoisting and all pulling or fence stretching purposes, and the present invention combines in a single tool a construction adapted to accomplish the many hoisting and pulling operations necessary in ordinary farming and wood cutting.

The invention has for an object to provide a novel and improved construction of windlass support having divergent sockets to receive supporting standards and a yoke formed with. bearings for the windlass shaft,

whereby a simple and efiicient construction permits the convenient assemblage and operation of the tool.

Another object of the invention is to present an improved form of brace socketsecured to the standards for the connection thereto of a brace member at an acute angle, together with a connecting chainextending from one brace socket to the other, and adapted to lie above an object supported by the cable from the windlass.

A further object of the invention is to pro vide a novel construction of grapple comprising pivoted crossed jaws connected by links to a clevis which supports a bearing pulley over which the hoisting and pulling cable passes.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims. I a

In the drawings Figure l is a front elevation of the invention applied as a saw buck;

Figure 2 is a side elevation of the same;

Figure 3 is a similar view of the tool used as a crane;

Figure 4: is a like view showing the tool arranged for pulling or wire stretching purposes;

Figure 5 is a detail of the windlass support; and

Figure 6 is a similar view of the brace socket.

Like numerals refer to like parts in the several figures of the drawings.

The combined tool as herein disclosed comprises the windlass support 10 having the oppositelydivergent sockets 11 adapted to receive the upper ends of the standards or legs 12, and formed at its upper portion with a U-shaped yoke 13 provided at its free ends with bearings 14 for the shaft 15 of the windlass 16 to which one end of the hoisting or pulling cable 17 is attached. These bearings are open and connected by screws 18 by which they may be properly adjusted tothe shaft. The windlass is also formed with a" ratchet wheel '19 which cooperates with a retaining pawl 20 pivoted in bearing lugs 21 from one of the yoke members and normally held in contact with the ratchet by a tension spring 22; The windlass shaft is provided with the usual operating handles 23 as shown.

The standards 12 have secured thereto brace sockets 21 which are formed with an angular enclosing portion 25 to receive the diagonally disposed braces 26 which extend at an acute angle from one side of each standard. These sockets are secured to the standards and braces by any desired means,

such as bolts passing through such members. A holding chain 27 adapted to cooperate with the tongs 28, hereinafter referred to, in maintaining logs and the like to be cut, in a rigidposition, extends from one socket to the other and is preferably adjustably connected at one end so that its length may be varied as required by conditions of use.

The cable 17 carries a grapple or tongs 28 comprising the pivoted crossed jaws 29 provided at their connected end with links 30 extending through a clevis 31 having a bolt 32 supporting a pulley 83 over which the cable is passed. This permits the use of the grapple as an engaging member at the end of the cable, as in Figure 1, or as a support for the cable when the latter is used as a crane or, for pulling purposes, as in Figures 3 and 4 respectively.

The invention is applicable to a wide variety of uses, but several particular applications thereof are herein disclosed. The tool may be used as a saw buck with the cable and grapple supporting a log or timber, and

if the latter be of short length the holding chain may be passed over the sameto afforda firm support during the sawing operation. When the tool is used as a crane, as in F 1gure 3, the side pulling of the cable uponthe standards is resisted by attaching the grapple to a fixed object. For post pulling purposes the grapple may be directly engaged with the post and the Windlass is properly retained by the braced standards. VVh'en used as a pulling or wire stretching tool the grapple is likewise connected to a fixed object and the horizontal plane of strain determined by a vertical adjustment thereof. It will therefore be seen that the invention presents a simple, efficient and economically constructed tool adapted for general use in farming and WOOdcutting operations.

lV hiztI-claiiriisp v 1-; In a toolofth'e' classdescribed; a wind lass support provided with divergent sockets and an upright yoke formed with bear ings, supporting standards disposed in" said sockets, a cable bearing Windlass. shaft carried by said bearings, abrace socket secured to one of saldstandards, and a brace disposedin said last named socket at an angle to one side of said standard, a grapple carried'by said OLbl6flll13tdft0 engage immovable objects on the far side of the supporting standards from the brace.

2i In a" tool-of the class described, supporting standards provided at their upper ends with a Windlass, a cable upon said Windlass, a, grapple carried by said cable and comprising pivoted crossed jaws, links from said jaws, a clevis connecting said links, and a pulley upon the clevis for said cable.

In a tool of the class described, supporting standards provided at their upper endswith a Windlass, a cable upon said Windlass, a grapple carried by said cable,

MARTIN GRAU.
